Marty has a box of raisins. He uses 1 1/2 cups of raisins for trail mix. Then he opens a bag with 2 1/3 cups of raisins in it. M

WITCHER [35]

Answer:

$5\frac{3}{4}\ cups\ of\ raisins$

Step-by-step explanation:

Let

x------> cups of raisins originally in the box

we know that

The original quantity is equal to the quantity that is left plus the quantity used

$x=3\frac{1}{2}+ 1\frac{1}{2}+\frac{3}{4}$

Convert mixed number to an improper fraction

$3\frac{1}{2}=\frac{3*2+1}{2}=\frac{7}{2}$

$1\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}$

substitute

$x=\frac{7}{2}+ \frac{3}{2}+\frac{3}{4}$

$x=\frac{10}{2}+ \frac{3}{4}$

$x=5+ \frac{3}{4}$

$x=5\frac{3}{4}\ cups\ of\ raisins$

Solve 3 ^ (x - 8) = 8 for x using the change of base formula logb y = (log y)/(log b)

Vilka [71]

Answer:

$x=3\log_3 (2) +8$

Step-by-step explanation:

Here we are using power rule first.

Power rule = The logarithm of an exponential number is the exponent times the logarithm of the base $[log(a)^{b}=b\times log(a)]$ .

For the function given.

$3^{(x-8)} = 8$ ,using log function both sides.

$(x-8)log(3)=log(8)$

Now,

$(x-8)=\frac{log(8)}{log(3)}$

Adding $8$ both sides.

$x=\frac{log(8)}{log(2)} +8$

And we know that $8=2^{3}$ so we can further write $log(8)=log(2^{3})=3log(2)$

Then we have $x=\frac{3\log(2)}{\log 3} +8$ .

Now, using change of base formula:

$\frac{\log y}{\log b}=\log_b y$

So, $\frac{\log 2}{\log 3}=\log_3 2$

Our final answer is $x=3\log_3 (2) +8$ .
